To all wiom 'l may] concern:

iis it known that I, ERNEST MAKER, a i' ot the United States, residing:it Chienne, County oi" Cook, and State of Illiois, be invented certainnew and useful i ments in Couplings, of whieh the ioliowing is :ispeoilieetion. 4

l .invention relaties to improvement-s in v for clamping togetherseetionsof hose, pipe, ete., and has for its object. the production ofsuoli ineens which shall be of improved construction and operation'.

The invention consists in the combination end znrrnngenient ot' partshereinafter' desoribed sind elainied.

"liie invention will be best understood by Herento to the accompanyingdrawings rorining e part of this specification, and in nf'bieh.,

The preferred form of Construction illustrated in. the drawingscomprises two abutting tubular members l and 2 adapted t ne seeured tothe ends of hose sections 3. so Tubular member l is provided at one sidewith integral adjacent -lugs 4 .in which e eylindr nl rotary member 5 ispivoted. A. bolt 6 is passed through member 5 eozentrieelly and eyes 7on the ene s of limbs 8 of the tssbnped link are secured to said bolt,as shown. Limbs 8 are. connected by yoke 9 end are provided withturn-buckles l() by oil? .Vhieh their lengths may be ed- 'B i.linainpiufr lever ll removably nnember 5 preferably by :i nd it?,tel-zing; into :i thread be weon lugs Lever ll inturued end 13 .adaptedthe '-ifle oif tubular member for the insertion of eis to assistinunlocking n. er t? provided with in 'eetions 1.5 adapted the @shapedlink, in; lever ll is so f oi relation to bolt t s Lower end lf3contests with iro line conne! ing the o er of outside. e axis 1on theparts are separation.

pposite to lugs 4 and projections 15 members 2 und l. are providedrespectively with an integral hook 16 und :in integral loop l? adaptedto deteehnbly engage said hook, The abutting end of tubular inen1- ber lis provided with en integrally Hering in position, the gasket beingcompressed lto tor-in nv tight JointJa By making the recess containing'the gasket 1.8 'flaring iinva-rdly danger of accidental" displacement ofsaid gasket is ebvizited.

lf desired, instead of the hook `and loop junction between one side ofmembers l and 2 the Clamping lever and link connection may be duplicatedon that side.

VWhile I have illustrated and described the preferred construction forcarrying my invention into effect this is capable of Varietion andmodification Without departing from the spirit of my invention.therefore, do not Wish to be limited `to the eXnet details ofconstructions-set forth, but desire to avail myself of such variationsand modiiontions as come Withinthe scope of the appended claims.

Having described my invention what it claim as new and desire to secureby Letters Patent is:
